Question type: Maintenance & Repair

I have already replaced the brake relay switch under the pedal, replaced both tail lights complete systems, replaced brake light plugs and replaced all fuses. I'm frustrated and need to fix this issue , I only have one tail light working , and my only brake light is the one on my cab. No turn signals ,no brake lights and only one tail light . Any suggestions???

Possibly loose ground to lighting circuit. Check for voltage at light sockets. Use frame as ground for tester. If voltage is there look for loose ground wire to frame.

Some of those GMC's use a circuit board for the rear lights. Go to RockAuto.com and look under "Body - exterior" then under "Tail lamp connector plate". Is that what you mean by "replaced both tail lights complete systems"?
